Description

Technical Field

[0001] The utility model relates to the technical field of power equipment and its accessories, and more specifically, it relates to a bare conductor protective cover for overhead cables. Background Technique

[0002] Overhead cables, as the main form of power transmission, are widely used in urban and rural power supply networks. However, the bare conductors of overhead cables are vulnerable to external factors such as wind, rain, solution pollution, and bird pecking in the high-altitude environment, resulting in the aging, corrosion, and even fracture of the wire insulation layer, and further leading to potential safety hazards and faults; the protective covers currently available on the market generally have disadvantages such as insecure connection, complex installation, and insufficient protection performance. For example, a wire protection device with the patent publication number CN219833677U has a complex installation. In the installation environment of overhead wires, after the operator installs the protection device on the wire, the locking and limiting of the fixing components need to be carried out. The installation operation of the protection device is cumbersome, and it is difficult to ensure the safety of the operator; therefore, we propose a new type of bare conductor protective cover for overhead cables, with simple installation steps, no need for additional operation to install fixing parts, and only need to place the male end and female end of the protective cover to complete the installation, so as to provide a better protection effect.

During the installation process, the first protective shell 13 and the second protective shell 14 are separated by a certain distance through an installation tool, so that the wire can be placed in the first protective shell 13 and the second protective shell 14. After the wire is placed between the first protective shell 13 and the second protective shell 14, the deformable elastic piece 15 restores the positions of the first protective shell 13 and the second protective shell 14 to the initial state, completing the installation. No additional connecting parts or fixing parts are required, and the installation is quickly set up through the deformable elastic piece 15; during the disassembly process, the wire is pushed out from the gap between the first protective shell 13 and the second protective shell 14 by pulling the pull buckle 4 through an installation tool, completing the disassembly.
